Pipeline Safety

What is Your Responsibility?

Natural Gas Lines

Natural gas is transported from production wells through large underground pipelines called transmission lines to regulating stations, usually near city limits. The gas then travels within cities and towns through main lines. From the main lines, natural gas is carried to your home or business through service lines, which stop at the gas meter. Only Columbia Gas of Massachusetts can repair hazardous leaks on gas service lines up to and including the meter. However, the property owner is responsible for repairing or replacing house lines that extend beyond the meter to the appliances in your home or business.

If buried piping isn’t maintained, it might become subject to corrosion and leakage over time. For your safety, we inspect gas lines for leakage on a regular basis. If the line is metallic, we also inspect it for corrosion. Our routine inspection covers all gas piping up to and including the meter.

In some circumstances, we are also required to test house lines and inspect gas appliances. If our inspection detects a problem in any portion of your house lines or any of your appliances, we might have to "red tag" the appliance and interrupt your service until you have had it repaired.

Only a qualified heating/cooling contractor or plumber should perform any inspection, installation, repair or replacement of house lines or appliances.
